CPT code 90960 – ESRD monthly physician management services

Key Takeaways

CPT code 90960 covers ESRD monthly management with 4 or more face-to-face visits in a calendar month. Use 90961 for 2-3 visits and 90962 for 1 visit.

ICD-10 N18.6 (end-stage renal disease) is the required primary diagnosis code. A missing or incorrect primary code is a common cause of CARC 16, which flags missing or invalid claim data.

Medicare reimburses 90960 as a bundled Monthly Capitation Payment – one payment covers all ESRD physician management regardless of visit count above the threshold.

Pabau’s claims management software, with its Claim.MD integration, supports electronic claim submission, real-time eligibility checks, and ERA receipt for 90960 claims.

CPT code 90960: Official description and quick reference

CPT code 90960 is published by the American Medical Association (AMA) in the Medicine section of the CPT code set.

It sits under the End-Stage Renal Disease Services subsection (90951-90970). Its official descriptor covers monthly ESRD-related services for patients 20 years of age and older. The code requires 4 or more face-to-face visits per month by a physician or other qualified health care professional.

What CPT 90960 covers: Included services and scope

CPT code 90960 bundles all ESRD-related physician management services delivered in a calendar month into a single Monthly Capitation Payment (MCP). The following services are included within the MCP and may not be billed separately in the same month by the same managing physician.

• Clinical assessment of the patient’s ESRD status at each face-to-face visit
• Dialysis adequacy monitoring and prescription management (hemodialysis or peritoneal dialysis)
• Medication review and adjustments related to ESRD management
• Laboratory result interpretation for renal function, electrolytes, and anemia parameters
• Care coordination with dialysis facility staff and other treating providers
• Patient and caregiver education specific to renal disease management

What is not included: Exclusions and separately billable services

Services outside the monthly ESRD management scope remain separately billable. These include acute inpatient hospital services, emergency department visits, and surgical procedures, including transplant services. Evaluation and management (E&M) visits for conditions entirely unrelated to the patient’s ESRD are also billable. When billing separately billable services in the same month, use the appropriate CPT code with a modifier if required by your MAC’s local coverage determination. Always verify current National Correct Coding Initiative (NCCI) edits before billing any code alongside 90960.

CPT 90960 vs 90961 vs 90962: Choosing the right ESRD monthly code

The 90960 series is visit-count driven. The managing physician’s number of face-to-face visits with the patient in the calendar month determines which code to bill. Selecting the wrong code is one of the most common denial triggers for ESRD monthly claims.

Visit count is determined by the managing physician’s own direct face-to-face encounters with the patient. Visits by mid-level providers do not count toward the physician’s threshold unless they meet incident-to or split/shared billing rules applicable to your MAC jurisdiction. Count visits from the first through the last day of the calendar month, not a rolling 30-day window.

How CPT 90960 differs from CPT 90935 and other dialysis procedure codes

CPT 90935 (hemodialysis procedure with single evaluation by a physician) is a per-session procedure code, not a monthly management code. The two code families serve different billing purposes and are not interchangeable.

The managing physician billing 90960 for an ESRD patient cannot also bill 90935 for the same patient in the same month. NCCI edits bundle the per-session hemodialysis codes into the monthly MCP payment. Confirm current edit pairs in the CMS NCCI table before each billing cycle.

ICD-10 codes used with CPT code 90960

ICD-10 N18.6 is the required primary diagnosis code for CPT code 90960 claims. N18.6 maps specifically to end-stage renal disease and satisfies Medicare’s medical necessity requirement for ESRD monthly management services. Using a less-specific CKD stage code such as N18.5 (chronic kidney disease, stage 5) in place of N18.6 will generate a claim denial. N18.5 does not confirm that the patient is on dialysis.

Verify ICD-10 code validity annually. The CMS ICD-10 codes page publishes the official update files each fiscal year. N18.6 has been stable, but secondary comorbidity codes shift with annual guideline updates.

Medicare reimbursement and fee schedule for CPT code 90960

Medicare reimburses CPT code 90960 as a bundled Monthly Capitation Payment under the ESRD physician services fee schedule. The payment covers all included management services for the month regardless of how many visits above the 4-visit threshold the physician actually delivers. Rates are set annually through the Medicare Physician Fee Schedule (MPFS) final rule and vary by geographic locality.

Use the CMS Physician Fee Schedule lookup tool to confirm the current national and locality-adjusted rates for 90960. The 2026 rates reflect the annual conversion factor update published in the MPFS final rule. Because rates are locality-adjusted, a nephrology practice in a high-cost metropolitan area will receive more than the national average. A rural practice will receive less. Always pull the rate for your specific Medicare Administrative Contractor (MAC) jurisdiction rather than relying on national averages.

Examples of MACs include Novitas Solutions (Jurisdictions H and L) and CGS Administrators (Jurisdiction 15). Noridian Healthcare Solutions (Jurisdictions E and F) and Palmetto GBA (Jurisdictions J and M) are others. Each MAC publishes local coverage determinations (LCDs) that supplement CMS national policy and can affect documentation requirements and coverage criteria in your region.

Documentation requirements for CPT code 90960

Documentation is the single most audited element of 90960 claims. Under general medical billing compliance and audit best practice, the medical record should clearly support all of the following before the claim is submitted.

• Date and count of face-to-face visits: Each visit must be dated and attributed to the billing physician in the record. Four distinct dates of service are required to bill 90960.
• Physician identity and NPI: The billing physician’s name and NPI must appear on the claim and match the documentation. Shared care situations require clear notation of which physician managed the patient each visit.
• ESRD diagnosis confirmation: The record must confirm N18.6 (ESRD) and document that the patient is on dialysis (hemodialysis or peritoneal dialysis).
• Clinical assessment per visit: Each face-to-face visit note must assess the patient’s dialysis adequacy. It should also list the labs reviewed and any management changes made.
• Care plan documentation: A current ESRD care plan, or documented review of an existing plan, must be present in the record for the billing month.

As a general audit best practice, avoid templating visit notes to the point where they can’t be told apart. Each note should reflect what happened at that specific encounter, including any changes to the dialysis prescription, medication adjustments, or patient response to treatment.

How to bill CPT 90960: Step-by-step submission guide

Billing CPT code 90960 correctly requires confirming visit counts, verifying diagnosis codes, and submitting complete claims before the end of the billing month. Follow this workflow to minimize denials.

1. Confirm visit count at month-end: Tally the managing physician’s face-to-face visits with the patient during the calendar month. 4 or more = 90960. 2-3 = 90961. 1 = 90962.
2. Verify ICD-10 codes: Confirm N18.6 is listed as the primary diagnosis. Add relevant secondary codes (comorbidities, dialysis dependence status Z99.2) as documented.
3. Select place of service: Use POS 11 (office) for office-based management visits. Use POS 65 (ESRD facility) when visits occur at the dialysis center. Confirm with your MAC if the patient is seen in multiple settings.
4. Attach modifiers if required: Shared care arrangements and certain MAC jurisdictions may require specific modifiers. Check current MAC guidance before submission.
5. Submit electronically via clearinghouse: Submit on CMS-1500 or the electronic 837P equivalent. Electronic claims via Claim.MD allow real-time eligibility verification and ERA receipt, reducing processing delays on ESRD monthly claims.
6. Track ERA responses: Monitor the electronic remittance advice for adjustment reason codes. A CARC 16 on a 90960 claim calls for correcting the flagged claim data and resubmitting.

Submit no later than the filing deadline for your MAC jurisdiction. For Medicare, the standard timely filing limit is one year from the date of service. Submitting within 30-45 days of the billing month-end reduces denial risk from eligibility changes or patient status updates. When submitting a clean claim, ensure the diagnosis pointer on each service line maps correctly to N18.6.

Common denial reasons for CPT code 90960 and how to fix them

Most 90960 denials fall into a predictable set of categories. Understanding the root cause of each lets billing teams resolve them quickly rather than resubmitting with the same error. Effective denial management workflows for nephrology practices should include a 90960-specific denial tracker.

CARC 16 denials on CPT 90960 claims: Causes and remedies

CARC 16 means the claim lacks information or has a submission or billing error. Payers usually pair it with a remittance advice remark code (RARC) that names the missing item. On a 90960 claim, it typically traces to missing or invalid claim data. Common culprits are an absent or incorrect primary diagnosis, wrong service-date data, or a missing or mismatched NPI.

To resolve a CARC 16, read the RARC on the remittance advice, correct the flagged claim data, and resubmit the claim. Visit notes aren’t sent with the claim, so a CARC 16 isn’t a review of the medical record. Keep note-based appeals for record-review denials, where the appeal letter states the number of face-to-face visits, references each note date, and attaches redacted copies. Understanding the range of common denial codes in medical billing helps billing teams build standard correction checklists for recurring CARC 16 scenarios. Where an appeal is needed, file it within the timeframe stated on the remittance advice to preserve your appeal rights.

Monthly Capitation Payment model: How ESRD physician reimbursement works

The Monthly Capitation Payment (MCP) model pays the managing physician one bundled amount per patient per month. The amount stays the same however many visits above the threshold occur. A physician who sees an ESRD patient 6 times in a month still bills 90960 once. That physician receives the same payment as one who saw the patient exactly 4 times.

CMS adopted the MCP model for ESRD because dialysis patients require ongoing, intensive physician management that does not fit a standard fee-for-service per-visit model. The capitation structure encourages comprehensive monthly management rather than fragmented visit-by-visit billing. It also simplifies the administrative burden for nephrology practices that see the same chronic ESRD patients repeatedly throughout each month.

• One payment per month per patient regardless of visit volume above the threshold
• Covers all ESRD-related management by the managing physician, including care coordination and medication management
• Does not cover dialysis facility services, which are billed separately by the facility under the ESRD bundled payment system
• Rate is locality-adjusted through the Medicare Physician Fee Schedule, not fixed at a flat national rate

Codes 90960-90962 cover a full calendar month of ESRD management. Some patients aged 20 and older receive less than a full month of management, such as when dialysis starts mid-month. For them, the managing physician reports the per-day code 90970 instead. Learning medical billing fundamentals for capitation-based codes differs from standard fee-for-service CPT coding, and ESRD practices benefit from training staff specifically on MCP mechanics.

Who can bill CPT code 90960? Eligible providers and supervision rules

The managing physician – typically a nephrologist – is the primary eligible biller for CPT code 90960. The managing physician is the one who oversees the patient’s ESRD care plan. That physician is responsible for the overall monthly management of dialysis and related services.

Nurse practitioners (NPs) and physician assistants (PAs) may bill 90960 under their own NPI when they serve as the managing provider. State scope-of-practice laws and CMS supervision requirements still apply. Incident-to billing under a physician’s NPI has three conditions. The physician must have provided the initial service and be present in the office suite during NP/PA visits. The physician must also stay actively involved in the patient’s care. Sometimes more than one physician co-manages an ESRD patient during the same month. In that shared-care arrangement, only one physician may bill the monthly management code. The physicians must determine among themselves who bills based on which provider furnished the majority of services.

Conclusion

CPT code 90960 is straightforward in principle but prone to preventable denials in practice. The visit-count threshold, the N18.6 pairing requirement, and the documentation standards are all points where a claim can fail. Each one can stop the claim before it reaches an adjudicator.
